Circulating Tumor Cells, Disease Progression, and Survival in Metastatic Breast Cancer

TLDR
The number of circulating tumor cells before treatment is an independent predictor of progression-free survival and overall survival in patients with metastatic breast cancer.
Abstract
Metastatic breast cancer (MBC) is considered incurable; therefore, palliative treatment is the only option. The biologic heterogeneity of the disease is reflected in its somewhat unpredictable clinical behavior. The presence of circulating tumor cells (CTCs) in patients with MBC about to start a new line of treatment has been shown to predict progression-free and overall survival. This prognostic value is independent of the line of therapy (eg, first or second line). Moreover, a multivariate analysis has shown the prognostic value of CTCs to be superior to that of site of metastasis, type of therapy, and length of time to recurrence after definitive primary surgery. These data suggest that the presence of CTCs may be used to modify the staging system for advanced disease. Larger studies are needed to confirm these data and evaluate the use of CTC detection in monitoring treatment and furthering our understanding of breast cancer biology when combined with other diagnostic technologies.

Isolation of rare circulating tumour cells in cancer patients by microchip technology.

TL;DR: The CTC-chip successfully identified CTCs in the peripheral blood of patients with metastatic lung, prostate, pancreatic, breast and colon cancer in 115 of 116 samples, with a range of 5–1,281CTCs per ml and approximately 50% purity.

Tumor Metastasis: Molecular Insights and Evolving Paradigms

TL;DR: The invasion-metastasis cascade is a multistep cell-biological process that involves dissemination of cancer cells to anatomically distant organ sites and their subsequent adaptation to foreign tissue microenvironments as mentioned in this paper.

Tumor cells circulate in the peripheral blood of all major carcinomas but not in healthy subjects or patients with nonmalignant diseases.

TL;DR: The CellSearch system can be standardized across multiple laboratories and may be used to determine the clinical utility of CTCs, which are extremely rare in healthy subjects and patients with nonmalignant diseases but present in various metastatic carcinomas with a wide range of frequencies.

Imaging in the era of molecular oncology

TL;DR: Advances in experimental and clinical imaging are likely to improve how cancer is understood at a systems level and should enable doctors not only to locate tumours but also to assess the activity of the biological processes within these tumours and to provide 'on the spot' treatment.

American Society of Clinical Oncology 2007 Update of Recommendations for the Use of Tumor Markers in Breast Cancer

TL;DR: Thirteen categories of breast tumor markers were considered, six of which were new for the guideline, and certain multiparameter gene expression assays not all applications for these markers were supported, however.

Reporting results of cancer treatment.

TL;DR: Recommendations have been developed for standardized approaches to the recording of baseline data relating to the patient, the tumor, laboratory and radiologic data, the reporting of treatment, grading of acute and subacute toxicity, reporting of response, recurrence and disease‐free interval, and reporting results of therapy.
